The breeding of upland rice with New Plant Type characters in relatively short time can be done by using anther culture technique. The technique has been recognized as a rapid and efficient technology for crop improvement. Plant materials used in this research were F1 crossing P1 (Fatmawati x Way Rarem), P2 (Fatmawati x SGJT-28),  P3 (Fatmawati x SGJT-36), P4  (Way Rarem x Fatmawati), P5 (SGJT-28 x Fatmawati), and P6  (SGJT-36 x Fatmawati). Media for calli induction (N6) and regeneration (MS) were according to Dewi methods (2003). The results of this study indicated that P3 (Fatmawati x SGJT-36) and P6 (SGJT-36 x Fatmawati)  from resiprocal crosses gave better response in anther culture than the others crosses for their calli induction and green plant regeneration. From the six F1 crosses, 348 (53.5%) spontaneous doubled haploid (DH) pure lines were obtained, six lines from Farmawati x Way Rarem, 13 lines from Fatmawati x SGJT-28, 187 lines from Fatmawati x SGJT-36, three lines from Way Rarem x Fatmawati, five lines from SGJT-28 x Fatmawati, and 134 lines from SGJT-36 x Fatmawati.  These lines should be evaluated and characterized for their agronomical and morphological  traits.    Key words: Anther culture, doubled haploid, callus induction, green plant regeneration
